The construction of the new bicycle tunnel under the N322 is in full swing. It is part of the high-quality bicycle route F2. This is a 15-kilometer-long bicycle route connecting Zaltbommel and ’s-Hertogenbosch. Thanks to the new bicycle tunnel, you will be able to cycle safely and smoothly under the provincial road N322 next year.

Timelapse construction bicycle tunnel N322 Zaltbommel

The N322 is open again

The preparation for this project started years ago. Before the construction of the bicycle tunnel could begin, several cables and pipelines were relocated. From 10 to 20 October 2025, the N322 was completely closed. This was necessary to construct the part of the new bicycle tunnel under the road. This work was carried out by Strukton Wegen & Beton. The road surface was removed, earthworks were performed, prefabricated tunnel elements were lifted in and assembled, and finally the road surface was restored. Since Monday morning, 20 October, the N322 is open again for all traffic.

Still much to do

Work on the bicycle tunnel continues intensively. After 20 October 2025, we will carry out the remaining works. We will construct the remaining part of the tunnel north and south of the N322. We will also connect the tunnel to the surrounding bicycle paths and dig the ditches. Traffic will experience little or no inconvenience from these works. The plan is to complete the project fully by May 2026.

Facts and figures

The tunnel will be approximately 30 meters long, 8 meters high, and 4 meters wide. During the construction of the underground part of the bicycle tunnel, we installed 24 tunnel elements weighing 31 tons each. A total of 1270 m3 of clay and 1840 m3 of sand was excavated.

Regional cooperation

We work together with the Province of North Brabant and the municipalities of Zaltbommel, Maasdriel, and ’s-Hertogenbosch, as well as the Cyclists Union on the high-quality bicycle route F2. The 15-kilometer-long bicycle route offers a fast, safe, and comfortable alternative to the busy A2. With the addition of a bridge near ’s-Hertogenbosch and a tunnel near Zaltbommel, the route will be even better in the future. The new bicycle tunnel at the N322 is an important part of this route and ensures a safe traffic situation when crossing the provincial road. Strukton Wegen & Beton is building the bicycle tunnel for us. More information about the project can be found on our website N322: bicycle tunnel.
